PICTURE.

Application filed February To all 'Lc/wm t 'may coa-cera.'

Be it known 'that I, Ciriiinrs IN. SAAL- nUiio, a citizen of the UnitedStates, and residing at New York, in the county oi Queens and in theState oi New York, have invented a certain new and useful Improvement inPictures. and do hereby declare that the tol- ]owing is a full, clear,and exact description thereof. n

My invention relates particularly to pictures so arranged as to give theeffect of motion, or change, when viewed.

The object ot' my invention istoprovide a picture which may be of largesize, and therefore, of such a nature that different portions thereofare viewed at very diiierent angles. but which is provided with insertscovering restricted areas, each of which areas is viewed substantiallyat a single angle, and each oi which areas gives the effect of motion orchange when the position of the observer changes. It has been foun dthat when it is sought to make large movable or changeable picturesformed by the location ol a series ot' lines in front ot a compositepicture made up of alternating lines taken from two or more differentpictures, an entire picture of large size made in this manner will notchange at once when the position ot the observer changes, as the anglesot' the different portions or the picture to the eye are different. Thisis due to the fact that the different portions of the pictures locatedbehind the lines all occupy the same angle with regard to said lines,while trom any given position of the observer the different portions otthe picture are located at different angles to the eye of the observer.

.This diiiculty is overcome by locating the movable or changeableportions of the picture only in restricted areas, in accordance with myinvention.

While my invention is capable of embodiment in many diiierent forms, forthe purpose of illustration I have shown only one form thereof in theaccompanying drawings, in which- F ig. l is an elevation of a picturemade in accordance with my invention,

Fig. 2 is a horizontal section through the same at line 2 2, and

F ig. 3 is an enlarged View of one of the inserts.

In the drawings I have shown a device comprised of a large picture l,located be- 7, 1917. Serial No. 147,274.

hind a. transparent line screen l, having a back-ground 2 including aview of any desired objects, and which is not intended to move or changewhen the picture is viewed. In the back-ground there is shown thefigure, 3, of'a cow. It for example, it is desired to have the head andthe tail of the cow move, said picture is provided with inserts l and 5made up of a plurality of alternating lines 6 taken from two differentpictures showing the head and tail of the cow in two differentpositions. In the background there may also be provided similar inserts7 and 8 indicating the moon and a milk pail. which may be arranged so asto make the face of the moon move and make the milk pail turn over.Furthermore, there mayr be provided a similar changeable insert 9containing letters 10 adapted to change their position in a similar way.

When the composite picture made as above described is viewed from anygiven angle, the back-ground 2 .is readily seen, and on the back-groundthe immovable figure 3 of the cow is also readily seen, and when thecomposite picture is viewed from a certain angle, the head and tail otthe cow, as well as the pail, the moon and the word Cow will be seen inone position, while if the position of the observer is shifted the head,tail, bucket, moon and word Cow7 will be seen in another position, sothat by the shifting of the position of the observer in this manner theparts of the picture contained in these inserts will be seen to move.However, inasmuch as each of the inserts comprises only a restrictedarea of the larger picture, the whole of this restricted area can onlybe seen in one position at a given time by the observer, which would notbe the case if the movable insert covered a larger portion of the entirepicture. If the entire large picture were made to be movable in thismanner, an unpleasant eiiect would be produced owing` to the fact thatthe different portions of the picture aie not changed or moved togetherowing to the different angular positions of the different parts of thesame to the line of vision. By means of my invention this disadvantageis obvia-ted, and the lpicture at all times assumes a natural appearancethroughout its entire area.

1While I have described my invention above in detail, I wish it to beunderstood that many changes may be made therein Without departing fromthe spirit of my invention.

I claim l. A picture comprising a View which is non-changeable whenpresented at diierent angles to an observer, an insert in said piotureand means whereby only the View presented by said insert changes whenthe angle or the observer' to the insert changes.

Q. A picture comprising` a large View which is non-changeable fromdifferent View points of an observer, an insert in said pioturedepicting,` a portion of the picture shown by the large View, and meanswhereby only the View presented by said insert changes when the angle ofthe observer to the insert changes, to produce the effect of motionbetween the View shown on the insert and the large View.

-`3. A picture which is non-changeable having an insert therein, vonlysaid insert coin-l prising a plurality or' sets' of alternating linestaken from a plurality or" pictures, and a linescreen located in Jfrontof the insert.

4. A large picture which is non-change able having an insert orrestricted area therein, only said insert comprising a plurality ot'sets of alternating lines taken from a plurality oit pictures, and aline screen located in iront of the insert.

n testimony that claim the 'foregoing I have hereunto set my hand.

CHARLES W. SAAL'BURG.
